A neurologist believes that Hillary may have epilepsy.To confirm this diagnosis the neurologist needs to record the overall electrical activity in Hillary's brain.The best way for the neurologist to obtain this information would be to use
A) a positron emission tomography (PET) scan.
B) electrical stimulation of the brain (ESB).
C) an electroencephalograph (EEG).
D) a computerized tomography (CT) scan.

Question

Quizplus · Accepted Answer

An EEG is the most appropriate tool for recording the overall electrical activity in the brain. It is a non-invasive test that records the electrical activity generated by the brain using electrodes placed on the scalp. It can detect abnormal patterns of brain waves, such as those associated with epilepsy. PET and CT scans provide information about the structure of the brain, but do not measure electrical activity. ESB is an invasive procedure that involves stimulating specific areas of the brain with electrodes, and is not typically used for diagnosing epilepsy.
